Research output: Chapter in Book/Report/Conference proceedingChapter


The proposed paper summarizes the accelerated pavement testing database obtained from various locations, including a database of recent studies. Test sections built as part of a study investigating the effect of new generation wide-base tire (NG-WBT 445/50R22.5) and dual-tire assembly (DTA 275/80R22.5) on flexible pavement response were used. These test sections were established at three different test locations throughout the U.S.-Florida, Davis-California, and Ohio State. Various instrumentations were installed at several locations within the pavement system to capture the most critical pavement responses. Instrumentations installed include strain gauges, pressure cells, thermocouples, multi-depth defloctometers, surface strain gauges, and strain gauge rosettes. Critical pavement responses, including strain at bottom of AC and stress on top of subgrade, were analyzed. Moreover, the effect of temperature, differential tire pressure, and near surface responses were investigated for NG-WBT versus DTA.
